Sell PLC Based Central HVAC Training Equipment Building Automation Education Solutions

DESCRIPTION / TECHNICAL SPECIFICATIONS

Presenting an educational ecosystem that fully replicates a full scale central air conditioning system, this equipment is designed to meet the demanding curricula of modern higher education and industrial training. By utilizing a PLC (Programmable Logic Controller) as the main controller, the platform seamlessly bridges data communication between a computer and the mechanical system, enabling real time visualization, collection, and analysis of running parameters. Trainees are afforded complete flexibility through dual control modes: a manual mode operated via buttons on the control cabinet panel, and a computerized automatic mode that paves the way for exploring intelligent control systems and building automation.

The structure of this equipment meticulously replicates a true central AC plant architecture, composed of several interconnected functional units. This includes the refrigerating unit as the heart of the system, a cooling tower for heat rejection, a simulated boiler unit as a heat supply system, a pump station managing the circulation of chilled and heating water, and a simulated room system complete with a fan coil unit as the final air conditioning point. This detailed, modular design provides a holistic understanding of how each component interacts and contributes to the overall system performance, an invaluable experience for future engineers and expert technicians.

The sophistication of this platform lies in its adaptive control and automation system. Equipped with two frequency converters, the system can dynamically regulate the motor speed of the chilled water pump and the cooling water pump. High precision temperature sensors measure the inlet/outlet temperature differences, and this data is processed through A/D and D/A modules to command the frequency converters. This closed loop mechanism simulates modern adaptive control systems aimed at achieving optimal energy efficiency, providing learners with profound insights into smart building technology and energy management.

The training programs that can be executed on this equipment are extensive, covering the entire spectrum of central AC operation and maintenance. Participants will master structural understanding, start and stop procedures, running parameter detection, and even advanced PLC programming for installation and debugging. More importantly, the electrical control cabinet is equipped with a dedicated fault setting area to train diagnostic and troubleshooting skills. Instructors can simulate various fault scenarios, challenging trainees to analyze and resolve issues just like a professional in the field, ensuring they graduate with the highest level of competence and confidence.
